[0002] With the rapid development of the energy storage industry, higher requirements are also put forward for the battery management system (BMS). Whether the BMS manages chemical batteries well directly determines whether the energy storage system can operate safely and stably. To solve the instability problem of chemical batteries, battery simulation units have emerged as the times require. A single battery simulation unit replaces a single chemical battery. In actual applications, several battery simulation units are required to form a battery simulation device. The composition of the battery simulation device is not just a simple series connection of battery simulation units. In order to ensure fast heat dissipation, several battery simulation units share a radiator. The radiator is a conductor with a metal structure. If the radiator does not perform insulation and withstand voltage treatment well while dissipating heat from the battery simulation unit, it may affect the normal operation of the MOS tube on the battery simulation unit, increase the thermal resistance, and reduce the heat conduction ability. Therefore, it is necessary to perform insulation design on the battery simulation units sharing the radiator.
